First Embodiment

FIG. 1 is a block diagram showing the structure of an image processing apparatus according to the first embodiment of the present invention.

Referring to FIG. 1, an image processing apparatus 100 includes: an image pick-up lens 10; a shutter 12 having a stop function; an image pick-up device 14 that converts an optical image into an electric signal; an A/D (analog-to-digital) converter 16 that converts an analog signal output from the image pick-up device 14 into a digital signal; a D/A (digital-to-analog) converter 26; and an image processing circuit 20. A timing generating circuit 18 supplies a clock signal and a timing signal to the image pick-up device 14, the A/D converter 16, and the D/A converter 26. The operation of the timing generating circuit 18 is controlled by a memory control circuit 22 and a system control circuit 50.

The image processing circuit 20 performs predetermined pixel interpolation and color conversion of data from the A/D converter 16 and data from the memory control circuit 22. The image processing circuit 20 performs predetermined calculation by using image data that is picked-up. Based on the result obtained by the calculation, the system control circuit 50 controls TTL (through the lens)-system AF (auto-focus) processing, AE (auto exposure) processing, and flash by pre-emission processing which control an exposure control unit 40 and distance measurement control unit 42. Further, the image processing circuit 20 performs predetermined calculation by using the picked-up image data, and further performs TTL-system AWB (auto-white balance) processing based on the obtained calculating result.

The memory control circuit 22 controls the A/D converter 16, the timing generating circuit 18, the image processing circuit 20, an image display memory 24, the D/A converter 26, a memory 30, and a compressing/decompressing circuit 32. The data from the A/D converter 16 is written to the image display memory 24 or memory 30 via the image processing circuit 20 and the memory control circuit 22, or directly via the memory control circuit 22.

The image data for display operation written to the image display memory 24 is displayed on an image display portion 28 via the D/A converter 26. The image display portion 28 includes a TFT (thin film transistor) type liquid crystal display device, and realizes the digital finder function by sequentially displaying the image data picked-up by using the image display portion 28. Further, the image display portion 28 can be switched on/off in accordance with an instruction from the system control circuit 50. Upon switching off the display operation, the power consumption of the image processing apparatus 100 is excessively reduced.

The memory 30 is a memory for storing a still image or a moving image that is picked-up, and has a sufficient storage capacity for storing a predetermined number of still images or a moving image for a predetermined time. Thus, in the panorama photographing or the continuous pick-up operation for continuously picking-up a plurality of still images, an image with the large volume can be written to the memory 30 at the high speed. Further, the memory 30 provides a working area of the system control circuit 50.

The compressing/decompressing circuit 32 compresses or decompresses the image data by ADCT (adaptive discrete cosine transform). The data after the compression or decompression is written to the memory 30.

The shutter 12 is controlled by the exposure control unit 40. The exposure control unit 40 has a flash light adjusting function in association with a flash 48. The flash 48 has a light projecting function of the AF auxiliary light and a flash light adjusting function. The focusing of the image pick-up lens 10 is controlled by the distance measurement control unit 42. The zooming operation of the image pick-up lens 10 is controlled by a zooming control unit 44. The image pick-up lens 10 is protected by a protecting unit 102 as a barrier and the operation of the protecting unit 102 is controlled by a barrier control unit 46.

The exposure control unit 40 and the distance measurement control unit 42 are controlled by the TTL system. The system control circuit 50 controls the exposure control unit 40 and the distance measurement control unit 42 based on the calculating result of the image data picked-up by the image processing circuit 20. The system control circuit 50 controls the image processing apparatus 100 based on the constant, variable, and program for operation which are stored in a memory 52.

A display portion 54 displays an operating state or message by using a character, image, or sound in accordance with the execution of the program using the system control circuit 50. The display portion 54 includes a liquid crystal display device and a speaker, which are arranged to one or a plurality of positions for easily viewing the operating portion of the image processing apparatus 100, and are structured by combining an LCD, LED (light emitting diode), and sound device.

The mode dial switch 60 sets the switching operation of functional modes including power off, auto-photographing mode, photographing mode, panorama photographing mode, play mode, multi-screen play/erase mode, and PC connecting mode. The shutter switch (SW1) 62 is switched on during operating a shutter button (not shown), which causes instructing the AF (auto-focusing) processing, AE (auto-exposing) processing, AWB (auto-white balancing) processing, and processing of flash by pre-emission. The shutter switch (SW2) 64 is switched on upon ending the operation of the shutter button, which causes instructing the start of a series of operations including the exposing processing for converting the signal read from the image pick-up device 14 by the image processing circuit 20, writing the image data to the memory 30 via the memory control circuit 22, developing processing using the calculation by the image processing circuit 20 and the memory control circuit 22, and recording processing for reading the image data from the memory 30, compressing the data by the compressing/decompressing circuit 32, and writing the image data to the recording medium 200 or 210.

The image display ON/OFF switch 66 sets the on/off operation of the image display portion 28. In the photographing operation using the optical finder 104, the power supply to the image display portion 28 is shut off by the image display ON/OFF switch 66, which saves the power consumption. The quick review ON/OFF switch 68 sets a quick review function for automatically playing the image data that is photographed just after the photographing operation. According to the first embodiment, the quick review ON/OFF switch 68 includes a function for setting the quick review function when the image display portion 28 is switched off.

The operating portion 70 includes a touch panel and various buttons including a menu button, setting button, macro button, multi-screen play next page button, flash setting button, one-shot/continuous photographing/self-timer switching button, menu moving plus (+) button, menu moving minus (−) button, play image moving plus (+) button, play image moving minus (−) button, photographing image quality selecting button, exposure correcting button, and date/time setting button.

The power is supplied from a power supply 86 to the power control unit 80 via connectors 82 and 84. The power supply 86 includes a primary battery, such as an alkaline battery or lithium battery, a secondary battery, such as a NiCd (Nickel Cadmium) battery, NiMH (Nickel Metal Hydride) battery, and Li (Lithium) battery, or an AC (Alternating Current) adapter.

The recording medium detachment detecting unit 98 detects whether or not the recording medium 200 or 210 is attached corresponding to connector 92 or 96. The connectors 92 and 96 are connected to interfaces (I/Fs) 90 and 94. The recording media 200 and 210 are recording media, such as a memory card or hard disk, and include recording portions 202 and 212, I/Fs 204 and 214, and connectors 206 and 216. The connector 206 is connected to the connector 92 and the connector 216 is connected to the connector 96.

According to the first embodiment, two interfaces and two connectors for attaching the recording media are provided. However, the number of interfaces or connectors is not limited to two and can be arbitrary. The interfaces and connectors may have the same standard or different standards. Further, the interfaces and connectors may be in the conformity of the standard of a PCMCIA card (Personal Computer Memory Card International Association (also called PC Cards)) or CF (Compact Flash®) card. Further, when the interfaces 90 and 94 and the connectors 92 and 96 use the standard in conformity of the PCMCIA card or CF card, the image data and management information in addition to the image data are transferred to another computer or peripheral device, such as a printer, by connecting communication cards such as a LAN (Local Area Network) card, modem card, USB (Universal Serial Bus) card, IEEE1394 card, P1284 card, SCSI (Small Computer System Interface) card, and PHS communication card.

A printer is connected to the image processing apparatus 100 according to the first embodiment. The image processing apparatus 100 includes a function for sending and directly printing the image picked-up by the image processing apparatus 100 together with the trimming information, enlargement/reduction printing information and printing setting information, such as the number of printing sheets. In order to accomplish the function, the printer connected to the image processing apparatus 100 includes a function for receiving the image picked-up by the image processing apparatus 100 and printing the received image. The functions of the image processing apparatus 100 include a function for setting the trimming information for cutting out a part of the printing image and printing it. The trimming information for cutting out a part of the display image is set by operating the key arranged to the operating portion 70 while displaying the corresponding image on the image display portion 28. The trimming information is set and then the set trimming information is stored in the recording medium 200 or 210 with a corresponding relation to the image. Specifically, the trimming information is written to a header portion of the image data. If the trimming information is linked to the image in the play operation, the trimming information may be recorded to another file of the image data with a corresponding relation.

The image processing apparatus 100 according to the first embodiment has a slide show (hereinafter, referred to an auto-play function) for reading a plurality of images recorded to the recording medium 200 or 210 and continuously playing the images automatically or manually. Upon playing the image recorded to the recording medium 200 or 210 by the slide show play function, the image display operation is controlled depending on the determination of whether or not the trimming information is set to each image read from the recording medium 200 or 210.

Next, a description is given of the auto-play operation using the trimming information according to the first embodiment with reference to FIGS. 2 to 4. FIG. 2 is a flowchart showing the sequence for auto-play operation using the trimming information in the image processing apparatus 100 shown in FIG. 1. FIG. 3 is a diagram showing an example of a setting screen for determining whether or not the auto-play operation is performed by using the trimming information. FIG. 4 is a diagram showing an example of the display operation of an intra-trimming frame using the trimming information in the auto-play operation shown in FIG. 2. The sequence shown in FIG. 2 is executed based on the program stored in the memory 52 by the system control circuit 50.

Setting whether or not the auto-play operation is performed by using the trimming information on a setting screen 301 is shown in FIG. 3. The setting screen 301 displays a setting item (display the intra-trimming frame) 302 for setting whether or not the auto-play operation is performed by using the trimming information. An ON button 303 is used for setting the auto-play operation using the trimming information, and an OFF button 304 is used for resetting the auto-play operation. The user sets whether or not the auto-play operation is performed by using the trimming information on the setting screen 301.

A description is given of the play operation upon setting the auto-play operation using the trimming information on the setting screen 301. FIG. 2 illustrates the auto-play operation using the trimming information. In step S201, the system control circuit 50 sets the image as the processing target to the first one, namely, a file No. n to 1. In step S202, the system control circuit 50 displays the image of file No. n. Then, in step S203, the system control circuit 50 determines whether or not the trimming information is set to the image as the processing target. When the trimming information is set, in step S204, the system control circuit 50 enlarges and displays the image in an area prescribed by the trimming information set to the image as the current processing target, namely, the image in the trimming frame and then advances the processing to step S205. On the other hand, when the trimming information is not set, the system control circuit 50 skips step S204 and advances the processing to step S205.

In step S205, the system control circuit 50 determines whether or not the processing ends for all of the images. If it is determined that processing has ended for all of the images (yes in step S205), the system control circuit 50 ends the processing. However, if it is determined that processing has not ended for all of the images (no in step S205), in step S206, the system control circuit 50 increments the file No. n by one to automatically display the image of the next file No. n. The processing returns to step S202 and the system control circuit 50 displays the image of the file No. n. Incidentally, in the continuous play operation by the manual operation, the user presses the key disposed on the image operating portion 70 which increments the file No. n and displays the next image.

Referring to FIG. 4, in the auto-play operation, the entire image 401 of the corresponding file No. n is displayed in step S202. When the trimming information exists in the image 401 in step S203, the image in the area prescribed by the trimming information, namely, the image in the trimming frame is enlarged and is displayed as an image 402 in step S204.

According to the first embodiment, in the auto-play operation, for the image to which the trimming information is set, the image in the area prescribed by the trimming information, namely, the image in the trimming frame is enlarged and is displayed. Therefore, the auto-play operation is effective without the complicated setting operation.

According to the first embodiment, when the trimming information is set, the image in the area prescribed by the trimming information is enlarged and is displayed. According to another display method, for the image to which the trimming information is set, the display operation may have three steps. That is, first, the image before the trimming operation is played, only the image in the area continuously prescribed by the trimming information is then displayed, and the image in the area is enlarged and is displayed. Thus, it is easily understand which area of the original image is trimmed.

The image processing apparatus 100 according to the first embodiment has the system structure in which the printer is connected via the communication unit 110, and the image is sent to the printer together with the printing setting information such as the trimming information and can directly be printed without a personal computer. Further, the image processing apparatus 100 according to the first embodiment may have another system structure in which a digital camera is connected to the printer via the personal computer, the printing setting information such as the trimming information is set on application software operating on the personal computer, and the auto-play operation and auto-display operation can be performed by using the trimming information on an external monitor connected to the personal computer.

Second Embodiment

Next, a description is given of the second embodiment of the present invention with reference to FIGS. 5 to 7. FIG. 5 is a flowchart showing the sequence of the auto-play operation using the trimming information in an image processing apparatus according to the second embodiment of the present invention. FIG. 6 is a diagram showing an example of a setting screen for setting whether or not the auto-play operation is performed by using the trimming information shown in FIG. 5. FIG. 7 is a diagram showing an example of the display operation of an intra-trimming frame by using the trimming information in the auto-play operation shown in FIG. 5. Here, the structure according to the second embodiment is the same as that according to the first embodiment and a description thereof is not repeated here. The sequence shown in FIG. 5 is executed by the system control circuit 50.

According to the second embodiment, unlike the first embodiment, it is set whether or not the set trimming frame is displayed and whether or not the display operation of animation is performed in the enlarged display operation of the image in the trimming frame.

According to the second embodiment, a setting screen 601 shown in FIG. 6 is used for setting whether or not the auto-play operation is performed by using the trimming information. The setting screen 601 displays a setting item (display the intra-trimming frame) 602 for setting whether or not the auto-play operation is performed by using the trimming information, a setting item (display the on-trimming frame) 605 for setting the trimming frame is displayed, and a setting item (display enlarged animation) 606 for setting whether or not the animation is displayed in the enlarged display operation of the image in the trimming frame. Here, an ON button 603 is selected for setting the auto-play operation using the trimming information and an OFF button 604 is selected for resetting the auto-play operation. When the auto-play operation is set by using the trimming information, the setting items 605 and 606 are set. When the auto-play operation is reset by using the trimming information, the setting items 605 and 606 are not set.

When the auto-play operation is performed by using the trimming information, referring to FIG. 5, in step S501, the system control circuit 50 sets the image as the processing target to the first one, namely, file No. n to 1. In step S502, the system control circuit 50 displays the image of a file No. n. In step S503, the system control circuit 50 determines whether or not the trimming information is set to the image as the processing target. When the trimming information is set, in step S504, the system control circuit 50 determines whether or not the frame display setting for displaying the trimming frame is on. If it is determined that frame display setting for displaying the trimming frame is on (yes in step S504), in step S505, the system control circuit 50 overlays and displays the trimming frame on the displayed original image. Then, the processing advances to step S506. On the other hand, if frame display setting for displaying the trimming frame is not on, i.e., is off (no in step S504), the system control circuit 50 skips step S505 and advances the processing to step S506.

In step S506, the system control circuit 50 determines whether or not the enlarged animation setting is on for displaying the animation in the enlarging and display operation of the image in the trimming frame. If enlarged animation setting is on (yes in step S506), in step S507, the system control circuit 50 displays the animation of an interpolated image for enlarging and displaying the image in the trimming frame. Then, the processing advances to step S509. If enlarged animation setting is not on, i.e., is off (no in step S506), the system control circuit 50 skips step S507 and then advances the processing to step S509.

In step S509, the system control circuit 50 enlarges and displays the image in the trimming frame. Then, in step S510, the system control circuit 50 determines whether or not the processing ends for all of the images. If processing ends for all of the images (yes in step S510), the system control circuit 50 ends the processing. If processing does not end for all of the images (no in step S510), in step S511, the system control circuit 50 increments the file No. n by one so as to display the image of the next file No. n. Processing then returns to step S502 and the system control circuit 50 displays the image of the file No. n.

If it is determined in step S503 that the trimming information is not set, in step S510, the system control circuit 50 determines whether or not the processing ends for all of the images. If it is determined that processing ends for all of the images (yes in step S510), the system control circuit 50 ends the processing. If it is determined that processing does not end for all of the images (no in step S510), in step S511, the system control circuit 50 increments the file No. n by one so as to display the image of the next file No. n. Processing then returns to step S502 and the system control circuit 50 displays the image of the file No. n.

In the auto-play operation, the entire image 701 (of FIG. 7) of the corresponding file No. n is displayed in step S502. In steps S503 and S504, the trimming information exists in the image 701 and the frame display setting for displaying the trimming frame is ON, a trimming frame 702 indicating the area prescribed by the trimming information is overlaid to the image 701 and is and displayed in step S505. The setting of the enlarged animation is ON in step S506, the interpolated image upon enlarging and displaying the image in the trimming frame is displayed as an animation image 703 in step S507. Then, the image in the trimming frame is enlarged and is displayed as an image 704 in step S509.

The display operation of animation shown in FIG. 7 is one example and the present invention is not limited to this. Further, in place of the display operation of animation, with another specific effect, the process for enlarging and displaying the image in the trimming frame may be displayed.

Third Embodiment

Next, a description is given of the third embodiment of the present invention with reference to FIGS. 8 to 9B. FIG. 8 is a flowchart showing the sequence of the auto-play operation using the trimming information in an image processing apparatus according to the third embodiment of the present invention. FIGS. 9A and 9B are diagrams showing an example of the image additionally having the trimming information as the auto-play operation and a played image thereof. The structure according to the third embodiment is the same as that according to the first embodiment and a description thereof is not repeated here. The sequence shown in FIG. 8 is executed by the system control circuit 50.

According to the third embodiment, unlike the first embodiment, only the image additionally having the trimming information is displayed. That is, the image additionally having no trimming information is not displayed and only the image additionally having the trimming information is displayed. For the image additionally having the trimming information, the image in the trimming frame is enlarged and is displayed.

According to another display method, for the image additionally having the trimming information, the display operation may have three steps. That is, first, the image before the trimming operation is displayed together with the trimming frame. Then, only the image in the area continuously prescribed by the trimming information is displayed or the image in the area is enlarged and displayed. Thus, it is easily understood which area of the original image is trimmed.

In the auto-play operation using the trimming information, in step S801 of FIG. 8, the system control circuit 50 sets the image as the processing target to the first one, namely, the file NO. n to one. In step S802, the system control circuit 50 determines whether or not the trimming information is set to the image as the processing target. When the trimming information is set (yes in step S802), in step S803, the system control circuit 50 enlarges and displays the image in the area prescribed by the trimming information set to the image as the current processing target, namely, in the trimming. Then, the system control circuit 50 advances the processing to step S804. When the trimming information is not set (no in step S802), the system control circuit 50 skips step S803 and advances the processing to step S804.

In step S804, the system control circuit 50 determines whether or not the processing ends for all of the images. If processing ends for all of the images (yes in step S804), the system control circuit 50 ends the processing for all of the images. If processing does not end for all of the images (no in step S804), in step S805, the system control circuit 50 increments the file No. n by one so as to display the image of the next file No. n. Then, the system control circuit 50 repeats the processing from step S802.
